The users are flooded of clean duplicated messages instead of a single one.


  • You receive two or more messages which appear to be identical.
  • All the messages are received from a wellknown and trusted domain.
  • All of the sender and recipient addresses are the same in the message headers and the message envelope.
  • The message ID is different for each copy of the message.



The mail server at the sender domain is re-delivering the same message.


Please contact the mail administrator at the sending domain for further assistance. There is a possibility the sender database is corrupted forcing the MTA to send multiple messages.
